desired succession and without changing the positions of thecolumn stops.

With this object in view my invention consists in providing the tabulating mechanism with several sets of column stops, the

- number of the said sets depending of the character of the tabulating work which is intended to be done on the particular machine. In ordinary cases the number of the sets of column stops will be two, three, four, or more. When it is desired to write 7 columns or items of a different arrangement on su'ccessivesheets or on the same sheet, the column stops of the different sets are set accordingly, and when changing from one sheet or from one arrangement of the columns or items to another one, all that is necessary is to adjust the tabulator stops into position for cooperation with either one of the sets of column stops.

For the purpose of explaining the invention I have shown the same embodied in a typewriting machine equipped with a tabulating mechanism of the Gorin type. But

I wish it to be understood, that my invention is not limited to the construction of the tabulating mechanism shown in the drawlngs.

In the said drawings Figure 1, is a vertical cross-section of the tabulating mechanism showing in addition parts of the typewriting machine directly associated therewith, Fig. 2, is a plan view of Fig. 1, Fig. 3, is a rear View of Fig. 1, and Fig. 4 is a detail view showing the scale disk and hand for indicating the position of the tabulator stop relatively to the sets of column stops.

As is known in the art, the tabulating 5 mechanism of the Gorin type is equipped with a number of keys and key levers which correspond to the different denominations of the numbers to be printed by means of the machine, and by depressing either one of the said key levers a stop bar connected therewith is raised into position for cooperation with the column stops. Thereby the carriage is arrested in such a position, that the number to be printed in the column appears in the position corresponding to its denomi nation. A tabulating mechanism of this type has been illustrated in the accompanying drawings.

Referring to the said drawings, the paper carriage a is equipped with a plurality of tabulating members or bars I) each of which is provided with a suitable number of column stops 0. As shown in the drawings, four tabulating members I) are provided. Below the tabulating members a plurality of vertically movable stops or bars d are located either one of which may be shifted into position for cooperation with the column stops. Each of the bars d is jointed to a key lever 6 having a key 6 at its front end. As shown all the tabulating bars cl are mounted in a rocking frame f, and they are guided at their lower ends on a transverse rod 9 passing through longitudinal slots 9' of the said bars. Thereby the rods d have a slight rocking movement on the transverse rod 9 and they are longitudinally shiftable thereon. Normally the bars d are held in their lower or inoperative positions by springs 7i attached with one of their ends to the said bars and with their opposite ends to relatively fixed parts of the frame 1.

The frame f and the bars d mounted thereon can be rocked on the rod g, so that the bars (Z can be brought into position for cooperation with either one of the sets of. column stops 0. To rock the frame f the following mechanism is provided: The frame is connected at both sides with two crank arms 70 secured to a rock shaft Z. To the latter a sector m is secured which is equipped with laterally projecting teeth on, engaged by a pinion n. The p nion is keyed to a shaft 0 disposed longitudinally of the typewriting machine and projecting with its front end to the front sideof the machine and above the key board. At its front end the shaft 0 carries a milled button 9 and a hand 9 moving in front of a scale 1'. The said scale is shown in detail in Fig.

tion marks provided on the scale 7'.

4. At the rear of the scale an arresting disk 8 is secured to the shaft 0 which is formed with circumferential notches .9 corresponding to the difi'erent positions of adjustment of the frame f and the bars d relatively to the sets of column stops 0 and to the indica- The notches s are adapted to be engaged by an arresting block t provided at the rear of the scale 1" and to lock the shaft 0, the pinion .11, the sector m and thereby the frame f and stop bars 01 in the adjusted positions. If it is desired to set the stop bars (Z into operative position relatively to either one of the sets of columns, the shaft 0 is slightly pushed inward by pressing on the milled button p, whereby the locking disk s is disengaged from the block if, and the shaft 0 can be rotated into the desired position. Such rotation is transmitted through the pinion n to the sector m, which is rocked thereby and takes along the rocking frame f and the stop bars d. The position of the stop bars can be read from the position of the indications made on the scale 1', and the hand 9 and the scale 1' indicate, whether the stop bars 62 are in position for cooperation with the first, the second, the third, or the fourth'set of column stops. After the stop bars (I? have thus been set, the button ;0 is released, whereupon the shaft 0 is retracted by a spring at into normal position and the block 25 is brought into engagement with one of the notches s. Thereby the tabulating frame f is again locked. As shown the spring '11, is constructed the form of a coiled spring which is laid around the rear end of the shaft 0 and bears with its front end against the pinion n and with its rear end on a relatively fixed part of the machine. If desired further notches 8 may be provided intermediate the'notches s, and

- the said notches may be used for setting the frame 7 and the bars a? in intermediate po sitions in which the bars 03 are in position for engagement with two adjacent sets of column stops 0. Therebythe column stops 0 of adjacent series maybe combined to provide for printing in a large number of columns. More particularly the column stops of the first set can be combined with the column stops of the second set, the column stops of the second set with those of the third set, and the column stops of the third set can be combined with those of the fourth set.

Above the tabulating members 6 which carry the column stops 2. sheet metal plate 1; may be provided which when set-ting the column stops is rocked upward into the position shown in dotted lines inFig. 1. When in its normal or horizontal position shown in full lines in Fig. 1, the said plate covers all the column stops of the tabulating members b, so that the latter can not be dropped.

of parts shown in the drawings, and that I various changes may be made without departing from the gist of my invention. For example, if only two sets of column stops are provided, the vertically movable stop bars d maybe arranged with their top ends between the tabulating members 6, so that they are brought into engagement with either one of the sets of column stops by slightly rocking the same.

The invention may also be used in tabulating mechanisms of different types.

I claim herein as my invention:
